Ingredients
Beef sirloin, thinly sliced (1 pound, substitute with flank steak or ribeye)
Bell peppers, assorted colors, sliced (2 large, use red, yellow, or green)
Minced garlic cloves (4 cloves, use 6 for stronger flavor)
Soy sauce (1 tablespoon, use low-sodium or tamari for gluten-free)
Oyster sauce (1 tablespoon, use vegetarian oyster sauce for non-shellfish option)
Sesame oil (1 teaspoon, add at end for aroma)
Cornstarch (1 tablespoon for beef coating and sauce thickening)
Vegetable oil (1 tablespoon, neutral high-smoke point oil)
Sugar (1 teaspoon, balances saltiness)
Salt and black pepper (to taste)
Instructions
Preheat a skillet or wok over high heat. Add vegetable oil and swirl to coat.
Add half the garlic and stir-fry for 30 seconds until fragrant.
Sprinkle cornstarch over beef slices, toss to coat.
Add beef to skillet in a single layer. Sear for 2-3 minutes until browned. Remove beef and set aside.
Increase heat to medium-high. Add remaining garlic and stir-fry for 30 seconds.
Add bell peppers and stir-fry for 3-4 minutes until tender-crisp but not softened.
In a small bowl, mix soy sauce, oyster sauce, sugar, and 1 tablespoon water. Add to skillet with peppers and bring to a simmer.
Mix in 1 teaspoon cornstarch dissolved in 1-2 tablespoons water to create a slurry. Cook for 1-2 minutes until sauce thickens.
Return beef to skillet. Add sesame oil and gently toss to coat in the sauce. Season with salt and pepper to taste.
Cook for an additional 1-2 minutes until beef is fully heated through.
Notes
For extra tenderness, marinate beef in cornstarch, soy sauce, and ½ tsp sesame oil for 10 minutes before cooking. Use a cast-iron skillet or wok for optimal high-heat searing. Leftovers refrigerate well for 3-4 days in an airtight container.
